Trackmania Nations Forever

This game is a crazy racing game with lots of high-adrenaline racing with Hot-Wheels style tracks and its FREE how about that?? Check out the website: http://www.trackmania.com download the Trackmania NATIONS forever game NOT the Trackmania UNITED one cuz for that you have to pay, but the nations ver.'s only limitation is that only 1 type of car isnt available. And some other features I think.
